Title: Filter regenerating device valve unit for internal combustion engine
Inventor: NOGUCHI MASAO
IPC: F02D9/04
Filed: 1995-02-13
Abstract: PURPOSE: To prevent direct discharge of particulate due to leakage through an exhaust valve and sticking of the butterfly valve of the exhaust valve by providing as a cutoff valve means with a butterfly valve and as an exhaust valve means with an elevation type valve. CONSTITUTION: Since, at a collection process, the ascent and descent type valve 33 of an exhaust valve means 22 makes surface contact with an opening type valve seat 32, the degree of shut off is high and leakage of gas is low. Further, since an exhaust gas pressure is applied in a shut off direction on the ascent and descent type valve 33 through a branch pipe by means of a first passage pipe, a contact pressure of the valve 33 is increased.  Since the valve bearing of the exhaust valve means 22 is formed of a high molecular type bearing material 37 being softer than the material of a valve stem 34, a problem, such as biting of the valve shaft 34 of the ascent and descent type valve 33 into the valve bearing 37 and sticking thereto during ascent and descent motion, can be eliminated even when a particulate material, such as soot, contained in exhaust gas is adhered and accumulated to the periphery thereof.

Title: Method and apparatus for preparing electrostatic recording head
Inventor: TOUDOU YOSHIMASA
IPC: B41J2/395
Filed: 1983-02-18
Abstract: PURPOSE:To make it possible to automate the formation of an insulating layer, by applying potential having polarity the same as that of a fine powder to the multi-needle electrode of an electrostatic recording head while applying potential having inverse polarity to a control electrode to charge and spray the fine powder prepared by solidifying insulating particles with a heat-meltable binder resin from a nozzle. CONSTITUTION:For example, voltage of +50kV is applied to a nozzle 15 from a power source E3 and a fine powder prepared by solidifying insulating particles with a heat meltable binder resin is sent under pressure from a tank 18 by a pump 17 to inject the charged fine powder to an electrostatic recording head. On the other hand, for example, voltage of +500V is applied to the multi-needle electrode of the electrostatic recording head from a power source E2 while voltage of -500V is applied to a control electrode 12 from a power source E1. Therefore, the charged and injected fine powder is repelled from the multi-needle electrode 10 and attracted and selectively adhered to the control electrode 12 and, thereafter, melted under heating to be integrated therewith. By this method, the local formation of an insulating layer to the electrostatic recording head can be automated and the mass production thereof can be easily performed.

Abstract: PURPOSE: To acieve reliable brake function, by providing a transmission ring on the rotary shaft while continuously pressure contacting the end face of said ring through a resilient member against the machine frame to provide brake function and releasing said pressure contact against resilient member with the rotation of shaft.  
     CONSTITUTION: When not rotating, the rear end outer-circumference 82 of transmission ring 8 idly inserted into the rotary shaft 5 is pressure contacted by the repulsion of resilient member 11 against front brake lining 13 of normal machine frame wall 12 to block the rotation. Here a pin 6 of rotary shaft 5 is engaged at the bent position of C-shaped engaging hole 7 made through bearing tube 3 contacting with rear end inner circumference 83 of transmission ring 8. When rotating the rotary shaft 5 to one direction, said pin 6 moves to the end portion of engaging hole 7 thus to push forward the bearing tube 3 forcefully and to push the transmission ring 8 against the resilient member 11 in the direction of arrow a, thereby rear end outercircumference 82 of transmission ring 8 is separated from the lining 13. Since the bearing tube 3 and the transmission ring 8 are coupled through a pin  9, the rotary shaft 5, bearing tube 3 and the transmission ring 8 rotate integrally.
